I am so confused, not sure what hand I am playing

[Snow White]

Ok in our 1 day apart my husband sent me probably 50 texts and a few phone calls - all of which I did reply to. Yesterday afternoon he asked that D and I come home tonight and we can try and make this work. I agreed and he called 2 times since and not at all since last night before bed (by this time yesterday I had heard from him 30 times) I want to go home. Question is what do I do when I get there. We have been back and forth with this OW and the fact that he won't contact her then he does. Do I just let it go completely and run its course? Do we try to talk about the R and what making it work entails? Am I piecing or being a doormat?
